CASTING APPARATUS.

To all whom it may concern:

Be it known that we, DAVID WV. BLAIR and FRANK LINDEN ANTIsELL, citizensof the United States, and residents, respectively, of Perth Amboy,county of Middlesex, State of New Jersey, and of the city, county, andState of New York, have invented certain new and useful Improvements inCasting Apparatus, of which the following is a specification.

In a general way and in its broadest aspects, the present invention maybe said to relate to the shaping of fluid metal or other plasticmaterial and to have for its purpose the most expeditious and economicalproduction of an article of predetermined shape.

In a more particular way, however, the invention relates to a method andmeans for producing shaped articles from fluid metal or other plasticmedia in a most expeditious and economical way by subjecting theportions of the same at the place or places where its surface changesfrom one plane or direction to another, to a cooling action suf ficientto chill or set it quickly at such place or places, leaving theremainder of the metal or other medium to cool and set naturally.

and while it is traveling in a mold to a place provided for itsdischarge from the mold, for example. Such a process and apparatus is ofspecial advantage in the formation from fluid metal, of plates or barshaving grooves or offsets, as for instance, anodes, serving in such caseto quickly chill the wall of such groove or offset so that the form ofthe latter is not destroyed even though the metal is then conveyed awayfrom this cooling means before it has become cooled and set throughout;and permitting one such cooling device to be used for a plurality ofmolds which travel relatively thereto, and the cooling of the remainingportions of the metal to proceed naturally and while the molds aretraveling, as already stated, with the metal to a place of discharge. Insuch case, moreover, the cooling device may not only serve to cool butalso to produce the groove or oflset in the metal. While thisconstitutes, perhaps, the most advantageous use of the presentinvention, yet its utility is not restricted to such use, for it may beadvantageously employed, for example, to cool metal at the corners orother parts of the molds or articles formed in the molds, without itselfproducing any particular Specification of Letters Patent.

shape, relying upon the mold to give the metal the full shape required.While this cooling device may in any case be considered to be a part ofthe mold, yet for the sake of convenience it is hereinafter termed acooling device, and the means which carries the metal is designated amold.

Having thus in a general way set forth the invention, the preferredembodiment thereof will now be described, but inasmuch as many changesmay be made in the detail embodiment herein shown and described, andmany apparently widely different variations of the invention may be madewithout departing from the spirit of the invention, the form of theinvention herein shown shall be interpreted as illustrative and not in alimiting sense.

In the drawings, wherein like characters of reference designate likeparts in the several views: Figure 1 is a plan view of part of anapparatus exemplifying what is at present regarded as the preferred formof the invention embodied for the production of anodes from fluid metal.Fig. 2 is a side elevation of the same looking in the direction of thearrow 2 of Fig. 1. Fig. 3 is a transverse section on the line 3-8 ofFig. 1. Fig. 4 is a side elevation of a plurality of cooling devices.

A designates a series of open molds, each of which is herein shown ascomposed of a body part 1 and a transversely widened end portion 2 ofless depth than the body part. lhe interior conformation of the mold issuch as to produce, in the part 1 of the mold, a plate having at one enda central depression, and in the part 2 of the mold ears or lugs whichproject laterally from the sides of one end of the plate. These ears orlugs are to be of less thickness, in the form herein shown, than themain or body part, for which reason, as already stated, the widened end2 of the mold is of less depth than the remaining part 1 of the loo 1,so as to permit the metal to quickly free 105 itself from the coolingdevice without liability of flowing from the main portion of the mold.or losing the shaped corner or offset produced by the coopera-tiveeffect of the mold portion 2 and the cooling device. 1,1,

These molds are connected with each other and caused to travel by anendless conveyer B having a suitable driving means, comprising forexample, the sprocket- B. The preferred construction of this conveyerconsists of a double series of links 3 and l at each side of the molds,said links pivotally connected with each other by the journals 5 andspaced apart to leave between the pair forming each series, a space inwhich a series of supporting wheels 6 for the conveyer and molds aremounted upon the journals atoresaid. These wheels travel upon tracks 7.The sides of the conveyer are suitably connected with the molds, themeans of connection herein shown consisting in extending certain of thejournals 5 into bearings 8 in the ends of suitable trucks or frames 6which carry the molds. This forms a simple and durable construction ofmold conveying means which operates with a minimum of friction andcauses the molds accurately to travel the path predetermined for it, thetendency of the conveyor to sag and of the molds or pans thereby toleave the path determined for them to traverse being overcome by thesupporting wheels and rails.

C designates the cooling device which, as herein shown, is formedseparate from the part A and is adapted as already stated, to extendacross the end of the mold immediately over the laterally widened andshallower end part 2 of the latter, resting upon the upper edges of thelatter or in the oitset formed at the junction of the two parts referredto. This device is internally cooled,

being for this purpose formed with an internal chamber 0 which extendslongitudinally of it and is adapted to be connected with inlet andoutlet pipes 9 and 10 by which water or other cooling medium may becirculated through it. It is held properly in the path of movement ofthe traveling series of molds preferably under the action of a weight11, herein shown as suspended from a rod 12, which is hung from an arm13 arranged to pivotally connect with each other the meeting, pivotedends of toggle levers 14 and 15. One end of each pair of toggle leversis pivoted to the cooler, as at 16, and the other end of each pair ispivoted to a suitable fixed support afforded, for example, by a wall asindicated at 17. The tendency of this weight is to press the coolerinwardly toward the center of the mold, but its movement in suchdirection is restrained. or limited, preferably by an arm 18 which issuitably attached by a pivot or otherwise, to the cooling device at oneend, and has its other end provided with a hook 19 which engages aholding arm or bracket 20 of resilient or rigid material, fixed to asuitable support, as the wall 17. The means described also hold thecooling device in horizontal position.

21 is a rod, one end of which is secured to the cooling device and theother to a fixed support or wall, not shown, to brace the cooling deviceand hold it steady as the molds pass under it.

In the operation of the apparatus herein shown, the fluid metal issuitably supplied to a mold while the described cooling device isoperativcly related thereto and the cool ing ettect of the latter on themetal. contiguous to it is such as to permit the mold almost instantlyto continue its travel to the place of discharge, cooling in itsprogress thereto. l Vhile in Fig. l we have shown only one such coolingdevice, it is apparent that more than one such may be employed and thatmay be arranged along the path of travel of the molds, either closetogether or far apart. in such event, the metal will be subjected to asuccession of cooling operations which may be desirable in many cases.It is further apparent that instead of using a continuous cooling devicewhere a plurality of separate parts in a mold are to be cooled, as forexample, the ears in the form illustrated, a plurality of such coolersmay be used for such mold. Thus, in Fig. i, there is shown a pluralityof cooling devices C C, which may be arbitrarily assumed to illustrateeither the idea expressed of embodying in the apparatus a series ofcooling devices at dififerent places in the travel of the molds, eachadapted to a single mold, or the idea. named oit embodying a pluralityof cooling devices for different parts of the metal in the same mold. Tohold the cool ing devices C C together, a rod 22 is provided, one end ofwhich is connected to each. of said devices.

It has been found desirable in some con structions to provide the moldsbetween the end portions 2, with a lug 2 in order to steady the twoblocks as the gap or depres sion in the mold. between the end portions 2pass under said cooling devices. In some cases, the same lug may be usedto steady the cooling device when only one of such devices is employed.

The operation and advantages of the invention will be readilyunderstood. without further description thereof.

It is to be definitely understood not only that the invention is notrestricted to the details illustrated, but also that the language usedin the following claims is intended to cover all of the generic andspecific features herein described and all statements or matter relatingto or bearing upon the scope of the invention which, as a matter oflanguage, might be said to fall therebetween.
